At first I was skeptical whether this charger cable does the job, because this products there were no reviews. And even more when I saw that this program is supplied from HongKong with FedEx, I have easily given up hope. But after about four days, the power supply was with me and served its full purpose. The battery is for my feeling a little light, but the laptop is charged completely and without any problems and that's the main thing. Therefore I forgive here five star. If what changes in the next few weeks, I will report it, of course;)
